To aZlwhom it mag concern: f

Be it known thatI, CHARLES Cqrrn'r'r, a citizen of the United States, residlng at Masontown, in the county of Fayette and State of Pennsylvania, have invented new and useful Improvements in Hose Clamps, .ofwhich the followin is a specification.

My present invention pertains to hose clamps, and it hasfor its general object to provide a locking and adjustable hose clamp embodying such a construction that it is adapted to fit hose of different diameters within certain limits, and is also adapted to be used to advantage without the employ ment of tools, screws, nuts or other extraneous devices.

To the attainment of the foregoing, the invention consists inthe improvement as hereinafter described and definitely claimed. In the accompanying drawings, forming part of this specification I v Figure 1 is a side elevation of the clamp constituting the preferred embodiment of my invention as it appears when closed;

Figure 2 is a similar view showing the clamp in open state. 1

Figure 3 is a plan view of the closed clamp.

Figure l is an elevation of one end of the Figure '5 is an elevation of the other end of the clamp. a 1

Figure 6 is a detail section taken in the plane indicated by the line 6-6 of Figure 5 and showing the fastening of the clamp lever.

Similar numerals ofureference designate correspondingparts in all'of the views of the drawings.-

Among other elements'my novel clamp comprises a resilient metallic band 1. lat

one end the said band 1 has a reduced terminal or tongue 2-, and at its op osite end the said band is bifurcated as deslgnated by 3'." The arms'of' the said bifurcation 3 are connected to a pin 4, and on the said pin 4: is fulcriimed a curvilinear clamp lever 5-the head of which is'cam-shaped and toothed as atedby 6. Fixed on the tongue 2 of toothed body carried thereby are, extended through the bifurcation 3 er thepband 2, as illustmw and are also extended through easily a to ti'g Havin .move'on thebandl so as to carry its bight portion towardand' from the band 1. In other words thesaid kee er loop 8 is adapted to swing toward and rom the band 1. ,j

- In the practical use of my novel clamp, the same is pressed about a hose until the a keeper loop 8 that is connected 'at9 tothe v toothed body 7 passes through the keeper loop 8 and is en aged b sald loop. The lever is then wor ed bee and forth until the clamp is tightened sufiiciently about the hose to be clamped, when the lever'is pressed laterally into engagement with the lever keeper 10 on the band 1 when the lever will be securely held againstcasual movement. To releasethe clamp it'is simply necessary to press thelever 5'laterally out of 'engagement with the keeper 10 and then swing the said lever away from the band land dlsen gage the keeper loop 1 from the body 7 when the toothed body 7, will be released and the clamp may be opened. Manifestl when the band 1 is made of resilient meta and the toothed body 7 is released from the of the loo It will that m novel clamp may be quickly an tted to and secured about hose of different sizes and that by virtue of the construction described. the clamp may be strongly applied with but little efl'ort so as t1 0 am the hose. en the lever 5 is disengage fromthe lever keeper 10, but little'eiiort will be necessary to disenga e thekeeper iloop 8 from the toothed bogfl. y

8. he apparent from the foregoing I have entered into a detailed description I of theconst'ruction and relative arrange-a ment of theaparts' embraced in the present and preterm embodiment of my invention in order to impart a full, clear and exact understanding of the said embodiment I do'not desire, however, to be understood as confining myself to the specific construction.

and relative arrangement of parts inasmuch as in the future practice of theinvention va rious changes and. modifications may be I made such as fall within the S00 e of inyin- 'ventioxi as defined in my appe'n ed claims,

I described my invention, what I claim an desire to secure by LetteraPatent,

1. A hose clam oomprising a resilient bandj having aire uced ton ue'at one end and also having its other en portion bifurcated, a body fixed on'said tongue of the band and having'an outer toothededge. eon

vex in the direction of its length and adapt- "ed to be passed through the ifurcation of the'band, a kee er loop connected to the band and movab e into and out of engage ment with said toothed body, a lever pivoted between 'the arms of the bifurcation inthe *band and having a toothed head, and a keeper-on the band and adapted to hold the a lever against swinging movement away fromtheband.* I

' 2.5 Alhose olainp" comprising a resilient band,' having a'longitudinal portion with an outer toothed edge convex in the direction of it's length, a 'kee er loopon the band to engage said toothe portion and a lever on the band and having a toothed head to engage said toothed portion of the band.

3. A hose clamp comprising a resilient band, having a longitudinal portion with an outer toothed edge convex 1n the direction of itslength, a kee r loop on the band to engage said toothe portion, a lever on the band and having a toothed head to engage said toothed ortion of the band, and a hoe r for sai lever, on the band.
